Genetic Technology (Precision Breeding) Bill

Lord Winston Excerpts

Report stage
Wednesday 25th January 2023 Lords Chamber

[Baroness McIntosh of Pickering (Con)]

I have nearly finished my remarks. I have some sympathy with the amendments from the Front Bench opposite and would like to hear a very good reason why my noble friend may be minded not to support them.

[Lord Winston (Lab)]

My Lords, I remind my noble friend Lord Krebs—and I call him my friend because I have huge respect for him as a scientist, a Peer and a contributor to the House—that one of the great outliers was Dr Oppenheimer at the time of the Manhattan Project, who afterwards recognised what had been released as a result of that. We know very well that every single piece of technology that humans have ever produced has a downside we do not expect, and do not recognise and predict at the time. I would argue that this is one of those examples of a technology, which we have a duty, as a House in Parliament, to examine extremely carefully. I am not sure we have done that yet, and I am not sure how we can do it very well.

[Lord Roborough (Con)]

My Lords, I declare an interest as a dairy farmer and as an investor in a number of agriculture-related businesses around the world. I also declare negligible scientific credentials, unlike many noble Lords who have spoken.

However, I believe that it is essential that farmed animals are included in the Bill without undue delay, and I am very much against any amendment which delays or removes these animals. I have previously mentioned in this House that I could raise the output of my herd by 23% were all my cows blessed with the same genetics as my best cow. As noble Lords have already mentioned, there are disease benefits. Another example is the Roslin Institute’s engagement in gene editing of salmon, which improves resistance to infectious pancreatic necrosis viruses. These are meaningful benefits and I agree that they also improve animal welfare.

I would also add that I do not entirely recognise the world that was described by the noble Baroness, Lady Bennett, earlier. Agricultural productivity continues to increase globally, powered largely by ongoing plant and animal selective breeding. I believe that we have an obligation to unleash this technology of precision breeding to further increase production globally and support a growing global population.

[Lord Winston (Lab)]

Before the noble Lord sits down, I wonder if he might be kind enough to comment on this, seeing as he wanted to breed his best cow with all the other cows to reduce genetic diversity. Can he tell me what happens if a virus comes along to which that herd is susceptible? What do you do then? That is the problem.

[Lord Roborough (Con)]

As a non-scientist, I am not sure that I have a good answer to that. I would rely on the vets.

[Lord Taylor of Holbeach (Con)]

I think my noble friend is quite right: we will depend on increasing productivity and will be able to do that only by breeding. The whole point of the Bill is selective breeding; actually, it is precision breeding. The noble Lord may well have this nightmare that we are releasing something ghastly into the world; I do not believe that is true at all. It is done because of objectives in the breeding programme, which is precise. This is just the sort of thing that I do—and I declare my interest as a horticulturalist, as the House well knows—when we are breeding bulbs and daffodils. But this is more serious; this is not about domestic gardening but is about feeding the world and making it possible for the diversity that exists in gene stock to be harnessed for greater productivity.

[Lord Winston (Lab)]

I do not want to argue with the noble Lord about this too much but, actually, I have to say that there is good evidence. For example, with gene editing and the operation called i-GONAD where you can change embryos, most of those animals look perfectly normal and would pass without their gene being changed, but it turns out, of course, that they do not actually fulfil the requirements that you eventually have for the gene. That is one of the problems. That is a serious issue because you change other genes; not as a result of editing them, but by having those other genes edited. That is a big problem.

[Lord Curry of Kirkharle (CB)]

My Lords, I will briefly respond to the noble Lord, Lord Winston, on that point. It is a fair question, which we do need to respond to: what happens if we narrow the gene pool and expose animals to genetic risk? There has been evidence in the past that by narrowing the gene pool in dairy cows, we have had lameness problems; there has been an issue in other species. That is because we have not properly understood; indeed, random breeding, as the noble Lord, Lord Trees, has said, has resulted in that kind of action. Through better understanding of the genes, and through ensuring that we retain as wide a gene pool as possible from which to choose, but being selective and more careful and intelligent about the use of those genes, we should avoid that consequence.

--- Later in debate ---

[Lord Krebs (CB)]

Obviously, I agree that the different parts of the genome serve different functions. As the noble Baroness said in Committee, when we were students, we learned about junk DNA. However, it is not junk DNA; it can play an important part in regulating the expression of other genes. I take the point.

[Lord Winston (Lab)]

I love the idea of the noble Lord’s field of wheat waving gently in the breeze and the sunlight, but does he not agree that certain genes in those wheat seeds are rather well conserved and, in fact, do not change? Indeed, certain genes are protected from mutation. Therefore, there is nothing to prevent us looking at analysis to see the frequency of certain mutations within the genome; perhaps we need to be doing that. The data there could be very useful in all sorts of ways.

[Baroness Bakewell of Hardington Mandeville (LD)]

My Lords, this group of amendments deals with technical scientific issues and moving whole or parts of clauses from the negative procedure to the affirmative. Your Lordships will know that I am not a scientist so I shall, I hope, avoid digging a hole for myself or getting caught in the crossfire.

Amendment 12, in the name of the noble Baroness, Lady Bennett of Manor Castle, would require the details of genome sequencing to be recorded in a publicly available register. If the processes outlined in this Bill are to be carried forward successfully, it will be necessary for farmers, producers and the public especially to have confidence in the process. Ensuring that there is transparency and visibility through a publicly available register can only help this process. The DPRRC was strongly in favour of such a register in its report of 2 December.

Amendment 13, also from the noble Baroness, Lady Bennett, seeks to make the whole regulation in Clause 3 affirmative. Currently, the Bill is silent on whether Clause 3 is affirmative or negative. I suspect that, as it currently stands, Clause 4(6) applies to the whole of the section headed “Release”.

I am grateful to the Minister for his amendments in this group. At Second Reading and in Committee, concerns were raised at the number of negative procedures in the Bill. The Minister has tabled government Amendments 14 and 15 to Clause 4, which would qualify the section on marketing and keep subsection (1)(b) as negative while the rest of this clause will be moved to the affirmative procedure. This is welcome and gives the opportunity for debate on the notification requirements if necessary. Perhaps the Minister can clarify in his response whether Clauses 3 and 4 are covered by his Amendments 14 and 15. If not, can he say what process is applied for Clause 3? I am sorry; I may have misunderstood what this is all about.

Amendment 16, to Clause 6(4), moves regulations on the precision bred confirmation from negative to affirmative. We welcome the Minister’s movement on this point. This is a sensible way forward and, again, gives the opportunity for further debate.

Government Amendments 24 and 25 are somewhat confusing. Amendment 24 indicates that the regulations under Clause 18(1) are to be affirmative, and Amendment 25 deletes “this section” and inserts “subsection (6)”. I think this means that Clause 18(1) is affirmative while the rest of the clause is negative, as Clause 18(7) has not been amended. I would be grateful for the Minister’s clarification. It is important for when we come to debate these things later to know whether it is affirmative or negative. Although these are technical amendments, they are very important and provide transparency in the Bill, which is to be welcomed.

[Lord Benyon (Con)]

My Lords, I thank the noble Baroness, Lady Bennett, for her Amendment 12, which would require details of the specific gene editing event and the whole-genome sequence of a qualifying precision-bred organism to be made publicly available for its release into the environment. The noble Baroness’s Amendment 13 to Clause 3 would require that regulations made under this clause to establish a public register containing this information are subject to the affirmative procedure.

It is not our intention to require breeders to include sequence data as part of their release or marketing notices. I have discussed this previously following an amendment tabled by the noble Lord, Lord Winston, in Committee. We have since had a very useful meeting with the noble Lord and our scientific advisors, ACRE, to explore why whole- genome sequencing information has limited value in most cases, and the noble Lord has not retabled his amendment on Report.

This type of information has limited value because there is a significant degree of genetic variation between individual plants and animals within a species, which is more or less the point that the noble Lord, Lord Krebs, was making. This amount of background noise means that the value in requiring whole-genome sequences is limited in terms of addressing regulatory questions; for example, questions about the precision-bred status of a plant or animal. Additionally, the release notice that researchers are required to submit to Defra will be in line with the requirements of the Genetically Modified Organisms (Deliberate Release) (Amendment) (England) Regulations 2022, which were agreed by the affirmative procedure.

Our intention is that information provided in release notices will be published on the precision breeding register and will include the relevant and necessary information about the precision-bred organism in it. We also intend to require developers to confirm that the organisms that they intend to release in research trials meet the criteria in the Bill. The technical details of this notice will be prescribed by regulations, prepared with input from the advisory committee appointed to advise the Secretary of State on the regulatory status of these organisms and, in accordance with the amendments to Clause 4 that I have tabled, our intention is that such regulations will be scrutinised using the affirmative procedure before they are made.

I hope that this reassures noble Lords and that the noble Baroness, Lady Bennett, is persuaded to withdraw this amendment and not move her additional amendment to Clause 3, which would specify the parliamentary procedure for the delegated power that her substantive amendment would insert.

I always pay particular attention to points raised on secondary legislation by the noble Baroness, Lady Bakewell. As a member of the Secondary Legislation Scrutiny Committee, she is very good at holding me to account on these. I did not quite understand her point about Clause 3 because there are no regulations in Clause 3 and therefore no requirement for it to be affirmative or negative.

We remain of the belief that the matters to be set out in the regulations under the powers in Clauses 4(3) and 6(2) are administrative in nature. However, the Government acknowledge that these provisions are of significant public interest. We have heard this previously in the House and the Delegated Powers and Regulatory Reform Committee has raised this as well. We have considered these matters closely and have decided to change the procedure from negative to affirmative for both powers. These changes will increase the scrutiny when these powers are used to prescribe the information which must be provided to the Secretary of State by a person who wishes to release or market a precision-bred organism. I hope that noble Lords feel that I was serious in Committee when I said that I had listened to them. I hope that they feel that this improves the Bill. Regulations under Clause 4(1)(b) would be administrative in nature, not of significant public interest, and will remain subject to the negative procedure. I hope that this reassures noble Lords.

Amendments 24 and 25 will increase the level of scrutiny when powers are used to prescribe information that must be included in the precision breeding register. The Government acknowledge that these provisions are of significant public interest. We accept noble Lords’ concerns about the level of scrutiny for such provisions. Therefore, we will change the parliamentary procedure from negative to affirmative for the power in Clause 18(1). Regulations under Clause 18(6) regarding the keeping of the register, which is an administrative matter and, again, not of significant public interest, will remain under the negative procedure.

[Lord Winston (Lab)]

My Lords, I thank the Minister for what he has just said, but can he answer this question about whole-genome sequencing?

When we first started genome sequencing, it was laborious, expensive, time-consuming, and so on. It is now a pretty rapid process and can be done without huge expense. Does the Minister not agree that one of the reasons for doing this is not just marketing—because of course there are different issues there, which is how we are addressing this—but the advantage of getting more knowledge about what we are doing? The advantage there would be seeing where things are moving within the organisms that we are trying to edit. That is important as a research tool because, ultimately, we are doing something that—admittedly—we do not fully understand, and this would greatly increase knowledge. Does he feel that this is a relevant point?

[Lord Benyon (Con)]

It is entirely a relevant point, and was much on our minds when we debated some months ago a research measure in secondary legislation to allow the development of plant precision editing but not for it to be taken forward to market. The noble Lord is absolutely right that this is fast-moving and that we therefore need to be clear about how we regulate: that we are regulating a research process and a process to take products to market. Ministers will have to be clear about the intention of the organisation taking that forward. I hope, through the changes that we made, that there will be greater parliamentary scrutiny, that people with real knowledge, particularly in this place, will be able to scrutinise that, and that the Secretary of State of the day will have the best available information about what is being taken forward and why—whether it is just for research. The point made by the noble Lord about the value of research of products that will never go to market, that it is just to understand a particular aspect of genomic sequencing, is crucial.
